FLEXIBLE PIPE-CONNECTION.

SPECIFICATION forming part of Letters Patent No. 428,186, dated May 20,1890.

Application filed April 23, 1889. Serial No. 308,311. (No model.)

To a, whom it may concern:

Be it known that I, IIERMANN VERING, a citizen of the State of Hamburg,residing at Hamburg, German Empire, have invented new and usefulImprovements in Flexible Pipe-Connections, whereof the following is aspecification.

My invention relates to flexible connections between two metal or otherrigid pipes, the

said connections consisting in a hose of leather, india-rubber, or othersuitable material; and its object is to make such connections moreresistant against irregular strains, to render the pipes capable ofbeing rotated by a force applied to one of them, and to prevent theconnections from being bent'to an injurious extent. For this purpose Icombine with the said hose a universal joint consisting of two pairs ofarms fastened to the respective pipes, so as to be directed toward eachother, and of a ring encircling the hose with suffioient play andpivoted at four points to the said arms. Besides this, each arm of onepipe is connected to the other pipe by a rope or chain having suchlength as to limit the bending of the hose. For preventing shocks fromoccurring in the .said ropes or chains springs, india-rubber cushions,or other resilient media may be combined therewith.

In the annexed drawing a pipe-connection carried out according to myinvention is shown in an outside view.

a a are the two metal pipes, and b is the hose which unites them. Toeach pipe are fixed two arms cl, and these arms are connected togetherby the ring 0 and four pivots 6, so that the arms form with the ring auniversal joint. Each arm (I is connected to a lug h on the oppositepipe (L by a rope g and a spring f, the parts 9 and f having togethersuch length as to prevent the hose from being bent more than is desired.

The pipes provided with the said connections are especially designed tobe used with dredgers for the conveyance of the dredged material bymeans of a current of water, and in case the pipes are kept floating onwater in which there is any wave motion or which is exposed to changingtidal-currents.

I claim as my invention- 1. A flexible pipe-connection consisting of twopipes ct, each having two arms (Z, directed toward each other, anintermediate flexible pipe portion 1), and a ring 0, encircling the hoseand connecting said arms by means of pivots a, substantially as and forthe purposes hereinbefore set forth.

2. A flexible pipe-connection consisting of two pipes a, provided withtwo arms d, projecting toward each other, an intermediate flexible pipeportion 1), ring 0, encircling the hose, pivots e, located upon saidring and forming a universal joint between said arms and ring, and theropes g, connecting each arm of one pipe to the other pipe,substantially as and for the purposes specified.

3. A flexible pipe-connection consisting of two pipes (1, provided withtwo arms d, proj ecting toward each other, an intermediate flexible pipeportion b, ring 0, encircling the hose, pivots e, placed upon said ringand forming between said arms and ring a universal joint, and ropes g,combined with springs f and connecting each arm of one pipe to the otherpipe to prevent shocks or jarring, substantially as set forth.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.

HERMANN VERING.
